The need for enzymes
Several types of enzymes are used in the printing and writing segment to achieve specific objectives. Typically, these include refining energy reduction, fibre modification, fines management and viscosity modification of starches.
Careful selection of the appropriate type of enzyme is of key importance as enzymes are used for specific objectives and in different areas of the paper making process.
- Refining energy reduction is an important aspect of paper making in fibres like softwood with high refining demand.
- Fiber modification, fibre development, vessels and fines management are important requirements for refining shorter fibressuch as hardwood, agro and mechanical pulps. A combination of chemical energy (enzymatic action) and mechanical energy (refining) usually offers the best solution in dealing with such fibres.
- Viscosity modification of starches facilitated by enzymes is the oldest enzyme application in paper industry and specific enzymes help achieve these objectives.
Dosage levels, feed locations, operating conditions vary based on wet end configuration of mills and desired objectives. Dosage levels typically range from 50 g/ton to 500 g/ton of paper produced. Dosage levels in starch vary from 50-100 g/ton of starch used.
